Changing WEP Key

Do any of you networking Gurus by any chance know how to change a WEP key
for any wireless network adapters?

Or know where I can find such information?


Thanks a lot!
Brian W

Your base station is what controls the WEP key that is used. You need to
match that on wireless devices on the LAN.

Sorry, it doesn't sound like it but I do know that I guess I missed
something.

I'm looking for a program or script to do it so I can automate it.

Thanks again!

That's in the base station, Brian. You would need to design something to
not only access the base station, but put the password in correctly. The
more you would spread access around, the less valid the WEP key would be, I
think.

Nope again, sorry, Chris.

Let me rephrase the question...

I'm lazy!

I don't mind changing the WEP key on the basestation.

What I want is a script or program that I can run on all my client machines
that would take a new WEP key as a parameter and change the key for the
Wireless adapter.

For example, I could go to a command prompt and type:

C:\>changemywep 12345678910

Then hit enter and POOF! the WEP key is changed, and the adapter is reset so
the new WEP can take affect..


How's that?

Thanks
Brian W

Beyond my realm of comprehension, Brian. LOL! I imagine it could be done,
but what does it take, maybe 30 seconds to change the key manually?

Sure, it only takes 30 seconds for you, or me, but what about the novice on
the network? and If I'm not there to do it...

I can change the WEP key on my router (not using an MS router). But if while
I'm changing the WEP key I drop the new key into, say a text file, Then I
can tell Novice Operator #1 to click icon X and it sees the file and changes
the WEP key on the workstation.

For that matter I could write an app the monitors a folder on a disk drive
or network location looking for the file with the new key and runs the app
to change the WEP key locally.

Since I've seen several references indicating the WEP key should be changed
on a weekly basis, changing 4 or 5 keys gets to be a pain. An if someone had
to maintain a network of 15 or 20 PC's imagine the problems.

OK, so I think of some crazy shit sometimes, but you have to admit,
something like this would be useful.


Thanks again, Chris.

Actually, for a small LAN you should get equipment that supports
WPA-PSK. WPA is much better than WEP. If you have 15-20 pc's, the best
route would be an authentication server (radius) and WPA. 15-20 is
normally outside the normal expected number of computers for a home or
even soho LAN.

OK, but I was just trying to make a point. I could still see a need to
simplify such a task.

For a SOHO or even a small company it may not be feasable to upgrade the
hardware all at once.

Thanks for taking the time anyway, Barb.
